How Lorazepam Works: The Mechanism of Action
Lorazepam functions as a main nervous system (CNS) depressant. Its main mechanism includes the enhancement of gamma-aminobutyric acid (GABA), the most widespread inhibitory neurotransmitter in the human brain.
When an individual experiences high levels of stress or stress and anxiety, neuronal activity in the brain becomes overstimulated. click here binds to specific benzodiazepine receptors on the GABA-A receptor complex. This binding increases the frequency at which the chloride channel opens, allowing more chloride ions to enter the neuron. The resulting hyperpolarization makes the neuron less most likely to fire, successfully slowing down the CNS. This procedure causes a soothing impact, relaxes muscles, and decreases the probability of seizures.
